those are some mad powerpoint skillz doc.

[@lindathompson4770]

Amazing! How on earth could anyone have figured this out!

[@samehtaha5232]

pls post more doctor

[@user-jhsoshxhs33]

The best

[@jessicadoan834]

Can you make a video comparing the action potential graph between these 2 types of cardiac cells please? Are their resting and threshold potentials different values?

[@TheNotedAnatomist]

Should be done by early next week

[@jessicadoan834]

@@TheNotedAnatomist you’re awesome! Thank you so much

[@sdmsdm7926]

oh God I hope my heart is doing well, I don't want to die right now....I have basically no idea of all the hard work it does for me all the time, I just know that every morning I say thank you God for another day on earth...

[@user-jhsoshxhs33]

❤❤❤

[@A3Kr0n]

I thank you from the distal regions of my Purkinje network.

😂

[@worldisbold7196]

If the sa node has automacity , so its mean the heart keeps pumping only with coronary blood supply even if we take the heart out of the boby

[@TheNotedAnatomist]

The SA node will keep firing but if placed in a solution high in potassium the contractile muscles will not be able to contract but as far as i know the SA node keeps firing.

[@brodi4564]

Yes they did this test on animal hearts and they determined as long as there is adequate metabolic and oxygen supply to the heart, it will keep beating

[@Life.with.Angela]

I’m here early🥳

[@gloriasims4967]

What does it mean when a doctor said you have a heart leak?

[@TheNotedAnatomist]

I imagine it is a leaky or faulty heart valve

Second attendance✋️💝

[@vince1229]

Any truth that serrapeptase dissolves Purkinje fibers?

[@TheNotedAnatomist]

Hmmm I don’t know

[@walterbray81]

Ugh. Okay give me 20 times without ads

[@omapep21]

3:05 sigh lmao

[@Syzyro]

As you can tell, doctors are also human :>
